[0002] With the continuous advancement of biological detection technology, sampling and testing pen devices are increasingly widely used in fields such as medical diagnosis, environmental monitoring, and food safety. Traditional sampling and testing pen devices mainly consist of a sampling rod and a sleeve. The operation procedure is as follows: after sampling, the sleeve is removed, and the sampling rod with the sample is inserted into a solution containing buffer solution for plate lithography.

[0003] However, market application experience has shown that this design has significant drawbacks: samples cannot be adequately flushed, and the sample and buffer solution are difficult to mix and lyse sufficiently, which directly affects the accuracy and reliability of the test results. Furthermore, current testing pens on the market generally suffer from a limited number of detection targets. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0049] like Figure 1 , Figure 2 and Figure 3As shown, the detection device provided in this embodiment includes: a sampling component 100, a container body 200, a container base 300, and a mounting component 400; the sampling component 100 includes a sampling body 110 and a sampling part 120 disposed on the sampling body 110. The sampling part 120 is used to obtain samples. In use, after the aluminum foil is removed, the sampling part 120 is exposed, and the sample is obtained using the sampling part 120.

[0050] The mounting component 400 is disposed inside the sampling body 110. The mounting component 400 is used to fix multiple test strips inside the sampling body 110, ensuring that after the liquid after the sample and buffer solution are fully mixed enters the sampling body 110, the test strips come into contact with the liquid for plate testing.

[0051] It should be noted that, in order to facilitate the observation of the test results of the test strip, the sampling body 110 is made of transparent material so that users can observe the test strip.

[0052] The container body 200 is connected to the container base 300. The container base 300 contains a buffer solution and is equipped with a sealing film 330. The sealing film 330 is used to confine the buffer solution within the container base 300. When the sealing film 330 is punctured, the buffer solution flows out from the container base 300.

[0053] The sampling section 120 is configured to penetrate the container body 200, pierce the sealing film 330, and extend into the container base 300 so that the buffer solution comes into contact with the sampling section 120 and flows through the container body 200 into the sampling body 110 to come into contact with the test strip.

[0054] It should be noted that the container base 300 has a cavity for holding buffer solution. After the sampling part 120 is inserted into the cavity, the buffer solution overflows from the cavity into the container body 200 and then enters the sampling body 110 for plate testing. Therefore, the volume of the cavity, the volume of the buffer solution, and the volume of the sampling part 120 must correspond to each other to ensure that the liquid can enter the sampling body 110 after the sampling part 120 is inserted.

[0055] The detection device provided in this embodiment has a sampling part 120 on the sampling body 110 and a buffer solution in the container base 300. In use, the sampling body 110 extends into the container body 200, so that the sampling part 120 pierces the sealing film 330 and is completely placed in the buffer solution, so that the sampling part 120 and the buffer solution are fully in contact and mixed. The buffer solution flows along the container body 200 into the sampling body 110 and fully contacts the test strip in the sampling body 110. The test strip is tested. Furthermore, due to the setting of the mounting component 400, multiple test strips can be fixed to realize the detection of multiple targets. This alleviates the technical problems in the prior art where the sample and buffer solution are not fully mixed, affecting the detection accuracy and preventing the detection of more targets.

[0056] Regarding the structure and shape of the sampling component 100, specifically:

[0057] like Figure 4 As shown, the sampling body 110 has a sampling protrusion 111 protruding from the end face near the container body 200, and the sampling part 120 is sleeved on the sampling protrusion 111.

[0058] Specifically, the sampling protrusion 111 has a stepped protrusion, that is, the sampling protrusion 111 has a first outer diameter segment and a second outer diameter segment. The side closer to the container body 200 is the second outer diameter, and the side farther away from the container body 200 is the first outer diameter. The first outer diameter is smaller than the second outer diameter. The sampling part 120 is fitted on the second outer diameter segment. The sampling part 120 is specifically configured as a sampling structure such as an absorbent cotton or a lint swab.

[0059] In an optional embodiment, the sampling protrusion 111 is provided with a liquid inlet hole 112, which is located at the central axis of the sampling protrusion 111 and is used to allow buffer solution to enter the sampling body 110.

[0060] In an optional embodiment, a vent 113 is provided on the end face of the sampling body 110 near the container body 200. The vent 113 allows the interior of the sampling body 110 to communicate with the container body 200, and the vent 113 also allows the liquid in the container body 200 to enter the interior of the sampling body 110 through the vent 113.

[0061] Regarding the structure and shape of the container body 200 and the container base 300, specifically:

[0062] The container body 200 is threadedly connected to the container base 300. Specifically, the container body 200 includes two structural parts: an insertion part and a connecting part. The insertion part and the connecting part are integrally formed. The insertion part is used for the sampling body 110 to be inserted, and the connecting part is used for threaded connection with the container base 300. Due to the threaded connection, the connecting part is set as a cylindrical structure, and an internal thread section 210 is provided on the inner wall of the connecting part.

[0063] In addition, since the shape of the sampling body 110 is adapted to the shape of the mounting component 400, for example, the mounting component 400 is in the shape of a cuboid and the sampling body 110 is in the shape of a cuboid. In order to facilitate the insertion of the sampling body 110, the part of the container body 200 away from the container base 300 is set as a cuboid structure with a cuboid insertion hole.

[0064] like Figure 6 As shown, the container base 300 specifically includes a liquid storage section 310 and a grip section 320; the liquid storage section 310 and the grip section 320 are connected to each other, and the container base 300 is an integrally molded structure; the liquid storage section 310 is provided with a accommodating cavity for storing buffer solution, and a sealing film 330 is used to seal the opening of the accommodating cavity. When the sealing film 330 is punctured, the buffer solution in the accommodating cavity flows into the container body 200 under the pressure of the sampling section 120, and then enters the sampling body 110 for plate testing.

[0065] In alternative implementations, such as Figure 7 As shown, the outer surface of the liquid storage section 310 is provided with an external thread section 311; the inner wall of the container body 200 is provided with an internal thread section 210; the external thread section 311 and the internal thread section 210 are threadedly connected.

[0066] Regarding the structure and shape of mounting component 400, specifically:

[0067] like Figure 8 As shown, the mounting component 400 is specifically a cuboid plate structure with multiple protrusions on it. There is a gap between two adjacent protrusions to form a positioning groove. The positioning groove is used for the test strip to extend into. A fixing nail 410 is provided on the inner wall of the positioning groove. The fixing nail 410 is inserted into the test strip, thereby fixing the test strip in the positioning groove.

[0068] In alternative implementations, such as Figure 5 As shown, the inner wall of the sampling body 110 is provided with positioning ribs 114. The positioning ribs 114 are used to restrict the movement of the installation component 400 so as to fix the installation component 400 in the sampling body 110.

[0069] Specifically, multiple positioning ribs 114 are provided. Positioning ribs 114 are provided on two opposite surfaces of the inner wall of the sampling body 110. The protruding positioning ribs 114 are close to the mounting component 400, thereby positioning the mounting component 400 in the middle of multiple positioning ribs 114 to fix the position of the mounting component 400.

[0070] In alternative implementations, such as Figure 9 As shown, the detection device also includes a cap 500; the sampling member 100 has an opening at one end away from the container body 200, and the cap 500 has a fixing slope 510 that can extend into the opening so that the cap 500 blocks the opening of the sampling member 100. The cap 500 is designed to block the opening of the sampling member 100 and prevent external contamination from affecting the test strip inside the sampling member 100.

[0071] Alternatively, the cap 500 can be screwed onto the sampling component 100 by means of threads, or it can be snapped onto the sampling component 100 by means of clips.

[0072] The detection device provided by this utility model has the following technical effects:

[0073] 1. Enhanced sample and buffer mixing efficiency: When the sampling body 110 is inserted into the container body 200, the sampling part 120 will pierce the sealing film 330 and be completely immersed in the buffer solution, ensuring that the sampling part 120 can fully contact the buffer solution, thereby improving the mixing efficiency between the sample and the buffer solution.

[0074] 2. Improved detection sensitivity and reliability: Since the sampling section 120 is completely immersed in and in full contact with the buffer solution, the buffer solution can flow along the container body 200 into the sampling body 110 and make full contact with the test strip located therein, thereby enhancing the detection sensitivity and consistency of the entire system.

[0075] 3. Supports simultaneous detection of multiple targets: The design of the mounting component 400 allows multiple test strips to be fixed within the same device, enabling simultaneous testing of various targets without the need to change equipment or repeat operations. This not only simplifies the experimental process and saves time and resources, but also expands the range of information covered by a single test, which is particularly beneficial for applications requiring simultaneous monitoring of multiple indicators.

[0076] In summary, this innovative design not only optimizes existing sample processing steps but also greatly enriches detection functions, providing researchers with a more efficient, accurate, and flexible detection tool.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
